-This inventionrelates to improvements in dispensing nozzle devices. The invention has particular reference to nozzles for use in connection with tank vehicles which dispense gasoline, fuel oil and the liketo the reservoirs or buried tanks of customers. The invention is likewise adapted for use in other fields.

, I The primary object of the invention is to provide a nozz'le with an automatically operable valve which will close in time to, prevent overflow of the receptacle to which liquid isbeing dispensed; Referring specifically to theabove indicated use of the nozzle on tank wagons, it may be pointed out that the customers receptacle is usually providedwit-h a single pipe throughwhich the fuel must be supplied and there is no means whereby i the operator may be kept advised'of the-exact depthof liquidin the subterranean-tank.

2e Moreover, thefiller pipe is usually located in .a grass plot which is whollg or partially destroyed inthe event of over ow. In order to guard not o'nlyagainst loss of the fuel but ,i also against damage to surroundingproperty it is; the purpose of. the invention to provide a nozzle designed to fitwi'thin an ordinary 1 Y filler pipe and operable entirely automatically whereby todispense with any requirement for careon the part of the operator.

the provision of means for tripping the valve with substantialimmunity against accidental operation .thereof means for holding the I valve open with great rigidity but readily responsive to the light pressure of a 1 float; meansfor guarding thefloat from direct action' or impact of the incoming stream of liquid; and means for setting the valvein an open position and visuallywindicating the trip action.- I

by a partition 18 which provides aguide for valve stem Maud protects float- 15 from direct The tube'12 is closed adjacent its lower end impact of the streamv of liquid dispensed.

Immediately above partition 13 are the ports 16 controlled by the valve sleeve lTto which stem 1/: is connected by means of atranse vers'e web 18. Figure '2 shows the valve in ts open position wherein it is supported above openings 16. Itwill be obvious that it released the valve will fall upon partition 13 to close portsltl, I

Below the -partition, the stem 14 is reduced in diameter by an annular groove 20 or" hour glass contour as clearly indicated in Figure 2. When theovalve and stem are in open positionthe groove 20 is engaged by the shorter ends ofthe two pawl levers 21 which are pivotedbeneath partitions 13 upon either side'oi the valve stem; The portions of the ably approximately in a common diametrical plane through the stem and the ports are so proportioned that although the curvature late freely and without binding toward a re leasing position indicated in dotted lines. "For therelease of the pawls 21 each'ot them is provided; with an elongated arm 22 offset in opposite lateral directions to clear the valve stem at either sidethereofi These armsproject to opposite sides of the device from'their respective fulcrums thus develop- V pawls which engage in groove 20 are pre te'r 1 LllQ float is 1 iade of some non-metallic material such cork, it may be desirable to provide a metallic disk 2'? thereon to reduce friction between the float and the bearing portions 28 of the lever pawls.

The device is set by lifting the valve to the open position in which it is shown in. full lines in Figure 2. The weight of arms of pawls 21 is such that the pawls will automati'cally grip the groove 20 when the groove registers therewith. initial setting may either b accomplished manually preliminarily to introducing th nozzleint'ol the filler pipe or else mechanical settin means may be provided, sum as the wire 28 which is connected with the valve and ed upwardly through the nozzle to issue therefrom through boss 29. The location of the handle portion 30 of wire 2 above the boss 29 will obviously indicate to the operator the position of the valve. V I

hen tank 5 is nearly full, the float 15 will be buoyed up and will contact the bearing portions 28 of the arms 22 of lever pawls 21, thereby oscillating said pawls simultaneously to a position shown in dotted lines in which the valve stem'will be released. The design is such that bindino is impossible in the re leasing movement or the ports.

When the pawls are adjusted to releasing position the valve stem and valve will fall to close, or approximately close the ports 16' and simultaneously to give visible indication of the closing movement by means of wire 28 a d handle 30. 7

It is extremely important to note that the float-does not directly actuate either the valve or the indicating means. It would be ill practical to novide within the dimensions of liller pi e 6 a float having sufficient buoyancy even to lift the indicator wire or rod 28, not to mention the valve. Consequently the. arrangement is such that gravity furnishes the power and the float merely controls the m ove ment. p a

Since it may be assumed that an operator will always be in charge of the apparatus, is broadly immaterial whether the valve or he indicator is relied upon. Either device alone-will prevent overflow. For the ear 9 reason, it is not necessary that the valve 1? should entirely out off flow. The float con trolled trip will operate before receptacle is entirely full andftheattention of the operparent both audibly and by reference to the flow meter of the vehicle.

The particular structures disclosed have been selected as merely illustrative of the possibilities and it will be obvious that many alternative means may be e mployed within the Scope L pnend d Q im I claim:
